WHEELGUARD.

Specification of Letters Patent. Patented Sept. 24, 1918.

Application flled' February 5, 1917. Serial No. 146,758.

To all whom it may concern:

Be it known that I, STEPHEN N. CANFnsLn, a citizen of the United States, residing at Holly, in the county .of Prowers and State Ii of Colorado, have invented certain new and useful Improvements in Wheel-Guards, of which the following is a specification.

This invention relates to wheels, and more especially it is a guard intended for application to either the outside or inside of a wheel such as is usually employed upon hay rakes and other agricultural machines, the purpose being to prevent the hay from becoming entangled with the spokes of the wheel or wound about the axle during the use and operation, of the machine.

Sometimes these wheels are quite'largc, and to cut a guard or shield in one piece from sheet metal would involve considerable 2o expense because extra wide sheet metal would have to be used. Again it often oecursthat these are the drivingwheels of the agricultural machine, and it isnot desired to. remove them from the axles on which they arefastened; and it becomes desirable that the guards or shields" applied to the inner sides of these wheels can be put on without removing the wheels themselves.

Having these considerations in mind, my so invention consists broadly-in making the guard or shield in two arts or sectionsfeach therefore possible. of ormation from stock sheet metal narrower in width than the whole; and cally' in the manner of forming these parts and applying them to the wheel and conmeeting them with each other.

A further object is to provide a shield formed of overlapped separate sections which may be applied to the wheel of the hay rake or other machine in such manner that the lappedod es'will be prevented from engaging or catc ing hold of the ha. or ass and drawing it. on to the axle o the wheel during the operation of the machine.

With the above and otherobjects in view ..which will be more fully referred to in the speeificatiom-my invention consists in can tain novel features of construction, combinationand arrangement of parts, as will be heremafter more fully described and pointed Oiltgj" the accompanying drawings:

sections are each slotted as indicated at 12,

- the slots extendin radially into the center Fig.

'and 4 Fig. 5 is a view of the other plate'or section.

Referring now more partieularl drawings, 1 indicates a wheel of t e usual configuration of those adapted for use in connection with agricultural machines and which are generally provided with peripheral horizontally extending teeth.;or abutments 2 as shown. ported from the hub l .w extensions or flan es 5, extending laterally on both sides of the hub .4 and beyond the rimfi of'the wheel. The bob 4 and extento the The s okes" 31am supich has tubular sions 5 have a bore 7 extending'therethrough into which the axle of the agricultural In'achine is adapted to be received.-

The shield or guard which forms the subjcct matter of my invention is made up of separate plates or sections 8 and 9. Each of these plates is formed as a round sheet metal disk with perhaps one third its area in the shape of asegment'removed therefrom to provide an abrupt ed e or cord 10 extending transversely of the to the center opening 11 thereof and in this way larger plates. can be -formed from a single sheet of metal than would be possible if theentire shield were 'made in one 'The chords 10 (if therespecti've disk openings 11, thus ividing the chords 10 and providing each disk with two separate edgeportions. The plate- 8 is divided by the slot into se arate edgeportions 13 and 14, while the pl into edge ortions 15 and 16. The edge-portion 13 0 plate 8 and edge-portion 16 of plate 9 are each bent or deflected from the disk body to a plane slightly out of the plane of the d1sk itself, to accommodate the edges .1501 14 as the case may be, of the adjacent disk, as illustrated more clearlyjn Fig 3 of the drawings.

In assembling alinement with the slot of the other plate, after which they are inoved toward each other until the central 0 enings 11 are brought into alinement wit each isk and in proximity,

ate 9 is in likemanner divided the polite the plates 8 and 9 are brought together until the slot of one plate is in gure 1 is an-edge view of a wheel,

other and form a center opening common to both plates. The assembled plates are then placed in position against the wheel 1. so that the flange 5 oi" the hub extends loosely through the center 11. When thus adjusted. the portion 13 of the plate H over-laps the portion 15 of plate EL while the portion 16 of plate ll over-laps the portion 14- ot' the plate 9. The assembled plates contact with and rest against the rim of the wheel and completely cover the space between the hub flange and the wheel rim so that not only the hub of the wheel but also the spokes are ment therewith.

shielded and no wisps of hay. grass or other matter can be blown by the wind or become otherwise entangled with the wheel so as to interfere with the proper and c'tlicient operation of the machine.

From what has been previously said it can readily be seen that each plate ttlltsfiillb ing a part of the guard or shield is loosely mounted upon the hub ot a wheel so that the latter is rcvoluble theretlu'ough without transmitting any rotary motion to the guard itself. llt'iwever. should it be found expedient to so fasten the guard to the wheel as to render it revoluble with the latter. any suitable means can be resorted to for securely fastening the separate plates to each othe' and to the wheel'so as to provide a uniform rotary movement of the shielding sections. In the present instance. thisis accomplished by providing upou' the inner face of each of the sections h and fl a latch bolt 10 and a spring clamp 20. The boltit) is pivoted to the portions H and '1? respectively of each section and is adapted to slide under the catch or clamp "30. wliirh is always opposite the bolt, when the sections are placed together, being for this purpose. located rtau-wardly ot' the shoulder 18, as shown. The catch'Qt) is of the usual lip and hump formation and securely retains the bolt when the latteris slipped into engagethus joinedt'rom slipping (iii the flange 5, the. latter may be threaded to receive the thus adapted to rotate in the direction the machine 18 traveling, it; is to be particularly To prevent the sections noted that the assembled plates St and 9 present no obstructions or interstices onto or in which the waving strands of hay or grass may be aught. since any possible crevices which may be formed between the overlapped sections of the two plates are made, by the position and arrangement of the plates. to open in a direction opposite to the direction of rotation taken by that portion of the plate in which the particular crevice or crevices may be located. In applying the shield to wheels not provided with lmb ex tensions as illustrated in the accompanying drawings. the plates may be just as readily supported upon the axle of the machine and the marginal edges of the plates lodged under the inner periphery of the wheel rim;

Although the loregoiug description illusstrates what might be termed as preferred embodiment of the invention. it is to be understood that various changes in the form, proportion and minor details of the construction. may he resorted to within the scope of the claims without in any way sacrilieing any of the advantages thereof.

Having fully described my invention what .I claim as new and desire to secure by Letters Patent is:

1. A wheel guard consisting of mating sheet metal sections whereof each comprises the major part of a circle and is slotted t'roiii-its chord to an opening at the center of said circle, the portions on opposite sides of the slot being deflected out of line, with each other. and means for connecting said sections when assembled with their openings registering.

2. A wheel guard consisting of mating sheet metal sections whereof each comprises the major part of a circle and includes a chord slotted radially to an opening at the center of said circle, that portion to one side of the slot being deflected out of the plane of the remaindt-n' of the section, for the purpose set; forth.

In testimony whereof Iafiix my signature in presence of two witnesses.
